I couldn't be less interested in a single stack compact 10mm Glock.
Based on my experience a G20 can be made to work reliably with full power 10mm loads, but it takes aftermarket parts and a lot of testing. Even with a 24# RSA, the slide velocity makes feeding from stock magazines unreliable. Would a lighter slide on a single stack gun be an improvement? That seems unlikely, but I suppose it's possible.
The recoil on a G20 with full power loads is already quite stout, and followup shots are relatively slow. Shooting a G36 size gun with heavy 10mm seems unpleasant at best.
But all that isn't the real reason I won't be buying one in the unlikely event that Glock releases it. Just a few of many reasons I want ~15 rounds plus another 15 round reload when I'm in the backcountry... I've had encounters with:
-3 cougars 10 feet away in NV
-3 bears up close in MT
-3 carloads of tweakers blocking my family's vehicle in OR
And, I would way rather have 15 rounds of 9mm than 6-8 of 10mm, especially because Lehigh XP 9mm loads are available.
I do wonder if the releases of all these single stack handguns is due to companies covering the possibility of a nationwide AWB...
